Ghana forward Jordan Ayew provided an assist in Crystal Palace 3-2 win against Cardiff City which automatically sent the Blue Birds to the Championship.
Cardiff needed to avoid defeat against the Eagles on Saturday in a bid to stand a chance ahead of the final round of the league.
However, they were dealt a big blow in the 28th minute after Wilfred Zaha combined superbly with Andy Townsend to open the scoring for the visitors.
A minute after the hour mark, Neil Warnock's side equalized through an own goal by Palace's right-back Martin Kelly.
But Crystal Palace regained their lead eight minutes later after Jordan Ayew plays in Michy Batshuayi, who shows great determination to get to the ball before a couple of defenders before blasting home form inside the box.
Andy Townsend netted the Eagles third goal of the game on the 70th minute mark before Bobby Reid pulled a goal for the hosts but it was not enough to save them from relegation.
Jordan was replaced by Max Meyer in the 78th minute.
